———————————————————————————-

wget http://download.powervps.com/clientexec/Clientexec.2.7.3.Ion.zip
wget http://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz

———————————————————————————-
Now To install ClientExec:

- The first step is to create a database. (You need to create a mySQL database, database
username, and database password.)

- Upload the entire contents of the zip file to your server in BINARY mode.

- Apply any patches as needed.

- Change CHMOD permissions on the config.php file to 666.

- Also modify the config file as per your database configuration.

- Point your browser to http://domain.com/install.php

- After the installation is complete, delete or move the install.php file

That is it. You should have a clean install and ready to go.

READ the CHANGELOG.txt file

1) First step in any upgrade is to backup your database. You can do so using an application
like phpmyadmin which is commonly found with your hosting control panel utilities.
NOTE: We can not stress this step enough. We can not help you easily with any issues to
your data unless you have a backup before any upgrade.
2) Unzip the contents of your compressed ClientExec file.
3) FTP to your server, which contains the domain of your ClientExec installation.
4) Remove all of your files except for:
config.php
license.php - If upgrading from 2.2.x you do not need to keep your license file
uploads/files - Do not remove this folder if you have files in your files manager
5) Upload all the content files from the ClientExec zip file. Ensure that you do not overwrite
config.php or license.php
6) Visit http://yourceurl/install.php and click on Upgrade. Follow the steps until completion.
7) If you are getting any error o the above URL then please check that you have change the file permission to 666.
Delete install.php.

Upgrading Notes:
-If you see the install option available when you run the install.php script then you need to
check your config.php and ensure that you didn’t overwrite by mistake.
-If you are upgrading from beta 2.2.x then you do not need to keep your license.php file prior
to running the upgrade.
-After you have upgraded your version of CE you can now delete your license.php file.
-After you have upgraded your version of CE make sure you remove your install.php file.
-If after upgrading you find that you have unauthorized version installed message do not stress,
just follow the instructions below on obtaining a new license.
-After each upgrade go to admin->settings->3rd party invoices to ensure all plugins are synched
properly

Hello,

If you trying to installed Zend optimize and ionCube Loader on plesk server .

After installing Zend 3.0.1 and ionCube Loader php -v returns this:
———————————————————————-
PHP Fatal error: [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0

Here solution of this problem

1) Please go to cd /etc/php.d/ directory , edit ioncube.ini file and comment following line

#zend_extension=/usr/lib/php4/ ioncube_loader_lin_4.3.so

2) Now open php.ini file and add following code

zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.1

zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.1

zend_optimizer.version=3.0.1

zend_extension=/usr/local/ioncube/ioncube_loader_lin_4.3.so

zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so

zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

(Note : Depend of php veriosn please change ioncube_loader_lin_4.X.so file )

Problem fixed …….

Enjoy ………………….

What is mod_ruby?

”mod_ruby embeds the Ruby interpreter into the Apache web server, allowing Ruby CGI scripts to be executed natively. These scripts will start up much faster than without mod_ruby.”

1) Install eRuby

# wget http://www.modruby.net/archive/eruby-1.0.5.tar.gz

# tar -xzvf eruby-1.0.5.tar.gz

# cd eruby-1.0.5/

# ./configure.rb –with-charset=euc-jp –enable-shared

# make; make install

2) Install mod_ruby

i)Download latest mod_ruby tar file

# wget http://www.modruby.net/archive/mod_ruby-1.2.6.tar.gz

# tar -xzvf mod_ruby-1.2.6.tar.gz

 # cd mod_ruby-1.2.6/

#  ./configure.rb –enable-eruby –with-apxs=/usr/local/apache/bin/apxs

# make; make install

ii)Edit apache configuration file ( httd.conf) and add following code

LoadModule ruby_module libexec/mod_ruby.so

ClearModuleList

AddModule mod_ruby.c

AddHandler cgi-script .rb

<IfModule mod_mime.c>

# for Ruby/eRuby

<IfModule mod_ruby.c>

# for Apache::RubyRun

RubyRequire apache/ruby-run

# for Apache::ERubyRun

RubyRequire apache/eruby-run

# for development

# RubyRequire auto-reload

# for add library

#RubyAddPath /usr/local/lib/ruby

# exec *.rbx as ruby scripts.

<Files *.rbx>

SetHandler ruby-object

RubyHandler Apache::RubyRun.instance

</Files>

# handle *.rhtml as eruby files.

<Files *.rhtml>

SetHandler ruby-object

RubyHandler Apache::ERubyRun.instance

</Files>

</IfModule>

</IfModule>

iii) Restart apache service on server

memcached is a high-performance memory object caching system intended to speed up dynamic web applications by alleviating database load.

memcached is meant to work in concert with something like the MySQL query cache, not replace it. The two implementations excel at vastly different things: memcached is an object cache, while MySQL provides a query cache.

memcached is extremely fast. It uses libevent, which provides a mechanism to execute a callback function when a specific event occurs on a file descriptor, to scale to any number of open connections. On a modern Linux system memcached utilizes epoll, is completely non-blocking for network I/O, ensures memory never gets fragmented, and uses its own slab allocator and hash table to achieve 0(1) virtual memory allocation.

How it install

curl -O http://www.monkey.org/~provos/libevent-1.1a.tar.gz
tar zxf libevent-1.1a.tar.gz
cd libevent-1.1a
./configure
make
make install
cd ..
curl -O http://www.danga.com/memcached/dist/memcached-1.1.12.tar.gz
tar zxf memcached-1.1.12.tar.gz
cd memcached-1.1.12
./configure
make
make install

Then add /usr/local/lib to LD_LIBRARY_PATH in your .bash_profile


LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

How it Works

First, you start up the memcached daemon on as many spare machines as you have. The daemon has no configuration file, just a few command line options, only 3 or 4 of which you’ll likely use:

# /usr/local/bin/memcached –d –l x.x.x.x –u nobody –m 32 –p 11000

This starts memcached as a daemon (–d) on the IP address and port specified with –l and –p, respectively, running as the user nobody (–u), allocating 32 MB for object storage (–m). You should adjust the amount of storage to suit your needs; many memcached installs run with 4 GB. Once you’re comfortable with your startup options, add the appropriate command to your startup scripts.

With memcached installed and running, it’s time to get PHP talking to the object cache. While multiple PHP API’s exists, the one in the PECL repository is recommended. If you’re running a newer version of PHP, installation is as simple as:

# pecl install memcache
